Solution 38856: About TI Rechargeable batteries sold through Amazon

How can I determine if a TI Rechargeable Battery purchased through Amazon is a genuine, TI Rechargeable Battery?

The only way to be sure you are purchasing a genuine TI Rechargeable Battery is to purchase it through Texas Instruments, a TI Instructional Products Dealer, or Amazon directly. If you purchase a battery from Amazon Marketplace, you are responsible for ensuring you are purchasing a TI Rechargeable Battery.  TI is not responsible for damage to a calculator in which a non-TI battery has been inserted. To ensure you are purchasing a TI Rechargeable Battery, look for the words “Texas Instruments” printed on the battery.
